Abstract

Abstract

Traditional reliability analysis methods are more restricted in the reliability application of digital I&C systems, and new reliability analysis methods need to be explored. Taking the digital emergency shutdown system as the research object, Markov/CCMT is selected to complete the failure modeling of the system, and the qualitative analysis result of the emergency shutdown system is obtained. On this basis, quantitative analysis is performed to obtain the failure rate of the system. The results show that the failure probability of the digital emergency shutdown system analyzed by the Markov/CCMT method is 1.3×10⁻⁶ h⁻¹, and the Marko/CCMT method has certain applicability in the reliability analysis of the digital I&C system. Compared with the traditional reliability analysis method, Markov/CCMT method is more comprehensive in the expression of the dynamic characteristics of the system.
